US President Donald Trump has claimed that his administration secured “perhaps the largest” trade deal ever with Japan, unveiling new terms that include a 15 per cent reciprocal tariff on Japanese goods—down from the previously announced 25 per cent.

In a post on Truth Social, Trump said Japan has agreed to open its markets to key US exports including cars, trucks, rice, and other agricultural products. “Japan will pay Reciprocal Tariffs to the United States of 15%,” he stated.

Trump also claimed Japan has pledged a $550 billion investment in the United States, asserting that the US would receive 90 per cent of the profits from this deal—though he provided no further details. “This deal will create hundreds of thousands of jobs—there has never been anything like it,” he wrote.

The announcement comes as countries like South Korea are racing to finalize trade agreements with Washington to avoid heavy tariffs scheduled to take effect on August 1. Trump has previously threatened a 25 per cent tariff on Korean goods, particularly steel, aluminum, and automobiles.

Earlier this month, Trump reportedly sent a letter to Japanese Prime Minister Shigeru Ishiba stating that Japan would face 25 per cent tariffs unless a deal was reached. Tensions in the negotiations had been high, with Japan’s government hesitant to show flexibility ahead of recent parliamentary elections.

In a separate announcement, Trump also revealed a trade agreement with the Philippines, which will now face a 19 per cent tariff—slightly lower than what was previously indicated.

Trump’s aggressive tariff strategy continues to draw both praise and criticism as global economies seek clarity on future trade relations with the US.
